The BK series is a bare-bones machine, with no [[peripheral]]s or [[programming tool]]s. The only [[software]] available at the launch, except [[read-only memory]] (ROM) [[firmware]], is an included magnetic tape with several programming examples (for the languages [[BASIC]] and [[FOCAL (programming language)|FOCAL]]), and several tests. The ROM firmware includes a simple program to enter machine codes, BASIC and FOCAL interpreters.

While the BK is somewhat compatible with larger and more expensive [[DVK]] professional model [[microcomputer]]s and industrial [[minicomputer]]s like the [[SM EVM]] series, its 32 KiB memory, of which only 16 KiB is generally available to programmers (an extended memory mode supports 28 KiB, but limits video output to a quarter of the screen), generally precludes direct use of software for the more powerful machines. The DVK became a popular development platform for BK software, and most DVK software can be used directly with memory capacity extended to 128&nbsp;KiB.

Hobbyist developers quickly filled this niche, porting several programming tools from DVK and [[UKNC]]. This led to an explosion of homebrew software, from [[text editor]]s and [[database]]s to [[operating system]]s and [[video game]]s. Most BK owners expanded the built-in RAM to at least 64 KiB, which allows easier software porting, and as these upgrades often include [[floppy drive]] controllers, individuals creating [[disk operating system]]s became something of a competitive sport in the BK scene. Games and [[demoscene]] communities also flourished, as its poor graphics are offset by a powerful CPU.

One of the [[operating system]]s was [[ANDOS]], although officially the computer shipped with OS BK-11, a modification of [[RT-11]].
